To all whom it may concern: I

Be it known that I, HENRY W. FanKER, a citizen of the United States, residing at Ashland, in the county of Schuylkill andtank to effect the separation of slate and other foreign matter from the coal.

The'primary object of the invention is to provide a coal washer or jigger, the construction of which is such that the separation of the slate and other. foreign matter from the coal may be effected in a more thorough manner and in less time than heretofore.

A further object is to provide a novel form of jig pan or screen, and means for receiving the impact of the slush and coal at the feed end of said pan.

A further object is to provide the jig pan or screen with overhanging side plates which extend partially across the pan at the I discharge end thereof and serve to prevent the material from falling between the sides of the pan and the controlling gate and obstructing or otherwise interfering with the operation of the latter.

A further object is to provide the discharge end of the pan with a vertical plate or abutment on which is pivotally mounted a discharge spout, thus to permit the pan to oscillate in the washing tank without interfering with said spout. v A still further object of the invention is generally to improve this class of devices, so as to increase their utility, durability and efliciency.

Further bjects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

' For a full understanding of the invention and the merits thereof, reference is to be had to the following description and accompanying drawings, in which:

Corresponding and like parts are referred to .in the following description and indicated in all the viewsv of the drawings by the same reference, character's.

The improved machine forming the subject matter of the present invention com prises a supporting frame including upper and lower longitudinal sills 5 and 6 con nectedin any suitable manner by spaced uprights 7. Mounted on the supporting frame, is a stationary washing tank 8, the front end of which is forms by a transverse partition 9, while the rear end thereof is inclined downwardly at 10 in the direction of the bottom 11. Secured to the upper longitudinal sills 5 are bearings 12 in which is mounted for rotation an actuating shaft 13, the latter being provided with spaced hangers 14 having eccentric strapsl engaging suitable eccentrics 16 on the shaft, as shown. Suspended fromthe hangers 14,- and mounted for both vertical and horizontal movement within the washing tank 8, is a jig screen or pan 17 adapted to receive the coal and slush fromla feed spout 18, the latter being pivotally mounted at 19 on the longitudinal sills 5 at the rear end of the jig screen, as best shown in Fig. 1 of the drawings. A second shaft 20 is preferably journaled on the sills 5 and connected with the feed end of the. jig screen by spaced loops or hangers 21 so that when the shaft 13 is actuated, a gyratory movement will be imparted to said jig screen.

' Interposed between and secured in any suitable manner to the side walls 22 of the jig screen, is a frame 23 of the construction shown in Fig. 4 of the drawings. The side bars of the frame 23. are cut-away to produce a series of steps 24: on which are mounted perforated plates 25 which constitute thehottom of the jig screen. ing the bottom of the jig screen 1n this manner, when the pan or screen is operated. the steps 24 will impart a rolling movement to the coal over the bed of slate in the bottaken ontheline 2-2 of Fig. 1 and looking the. direction'of the arrow; Fig. 3 isa" By formvided with a contracted portion 27 terminat-' ing in a transverse bar 28 having oppositely disposed lugs 29 for attachment to the lower edge of the side walls 22 of the pan, which lugs are provided with inwardly extending bearings 30 adapted to receive the rock shaft 31 of a controlling gate The controlling gate 32 is provided with a perforated hottom and oppositely disposed side flanges 33, the free'ends of the flanges 33 being reduced and extended longitudinally to form spaced arms 34. g

Pivotally mounted at 35 with the free ends of the arms 3%, are vertically disposed rods 36, the upper ends of which project through guide plates 37 mounted on the upper edges of the side walls of the jig pan and are provided with terminal nuts 38, there'being coil springs 39 interposed between the nuts and guide plates 37 for normally and yieldably holding the gate 32 in closed position.

Disposed at the discharge end of the 11g pan or screen, is a vertical plate or artition' 40 having its upper end incline down' wardly at -11 and its lower end spaced from the transverse bar 28 to produce a discharge opening 42, which latter is normally closed by the gate 32. The plate or abutment 40 is provided with oppositely disposed attaching fian es 43 havin perforations formed therein for the reception of bolts or similar fastening devices and by means of which the abutment is rigidly secured to the screen. The inclined portion 41 of the'abutment is formed with half bearings 44: adapted, to re ceive trunnions 45 mounted on the spout 26, so as to permit free oscillation of the jig screen or pan within the washing tank, without affecting said spout.

Disposed Within the jig pan or screen, are side plates 46 of the construction shown in Fig. 5 of the drawings. Each side plate 4:6 is provided with an upstanding attaching flange 47 forpermanent connection with the adjacent side wall 22 of the pan or screen. and a downwardly inclined intermediate portion 48 which overhangs the gate and serves to prevent the material from dropping between the side walls of the pan and said gate and clogging or otherwise interfering with the operation thereof. Each side plate 16 is also provided with a depending .tlr a9 which overlaps and bears against the adjacent flange of the contmlling gate and is rigidly secured to the adjacent ends of the cont cited p rtion of the fram there bein I formed in the lower edge of t modate he rock gt; a. The per i placement of at .51 and gradually inerges'into the side walls of the pause as to form in effect a guide and assist in directing the slate and other foreign matter to the discharge openlng.

It willhere be noted that the lower'perforated plate constituting the steps, is interposed between'and bears a ainst the depending flanges 49 of the side p ates so as to assist in retaining said side plates'in position and also to assist in reventing accidental disthe adjacent perforated plate 25. a I

Seated in an opening in the bottom 11 of the washing tank, is a reversiblehopper 52 Q having oppositely disposed extensions 53, one of which pro ect-s within the tank, while the other-reg1sters with and forms a continuation of an inclined chute 54. Mounted forrotation in the hopper 52, is a sprocket wheel 55, over which passes the sprocket chain 56 of a coiiveyer, which chain also passes around a similar sprocket wheel '57 secured to a shaft 58 and is provided with spaced flights 59 which serve to remove the slate, slush and other foreign particles inthe hopper 52. The hopper 52 is provided with a discharge opening 60 normally closed by a sliding gate 61, to which gate is connected a rod 62 leading to a lever 63, so that by rocking the lever on its pivotal axis, the gate 61 may be moved to open or closed positions.

Arranged parallel with the conveyer 56,

is a similar conveyertil adapted'to receive the coal from a chute 65 and carry said coal to a suitable point of discharge. The con- 'veyer 64; is preferably of less len th than the conveyor 56 and isseparated rom the latter by a longitudinal partition 66'secured to the partition 9, as shown. g Extending inwardly from 'the opposite side walls of the jigpan or screen, are spaced flanges 67 between which is slidably inounted for vertical movement, a transverse plate or partition 68, the latter being preferably arranged. at an angle or inclinatio'nto the feed end 'ot' the screcn'and serving to receive. the impact of the coal and slush as the latter is fed into the an or screen. The partition 68 is adjusta le vertically of the jig pan or screen by means of threaded. bolts 69 connected withsaid partition and ex tending through a transverse bar 70.

l t will here be noted that the gate 32 is rear I able to the n of the 3 g pan or screen, thus eh'ectually preventing the accumulation of slate at the discharge opening and interfering with the 126 proper operation of the machine, the springs 39 serving to return the gate to closed position when the latter has been relieved of the weight of the bed of slate, as will be readily I understood. It will also be noted. that the 1 open or partially open position by ht cf the bed of slate in the bottom as to a suitable hopper 52 is reversible and forms a con.t1nu-- ation of the inclined wall 10 of the washing tank so that the slush, as well as the slate and other foreign matter deposited in the tank 8, will be directed into the hopper and thence conducted by means of the conveyer 56 to a suitable point of discharge; Thus it "will be seen that when the material isintroduced through the spout 18 into the jig pan or screen, the slate will gravitate to the perforated bottom of said pan, while the coal will rollover the top of the bed of slate and be discharged through the spouts 26 and 65 and deposited on the conveyer 64, the vert i-- V, '15 cal movement of the pan in the washing tank, causing the water to effect a thorough washing of the coal and theflseparation of the slate therefrom. The step ed portion 24 of the pan has the effect 'ot kicking or feeding the coal in a forward direction and also has a tendency to turn the light particles of slate within thejig pan and present 'said slate edge down, thus permitting the separation of flat or flake slate as well-as 25 cube slate. As theslate accumulates on the perforated bottom of the pan, the weight of the slate will open or partially'open the.

gate 32 and allow the slate to drop by gravity into the tank 8 and thence into the hopper 52 so as to'be taken up by the conveyer 56. During the gyratory movement of the jig pan or screen,-the free coal discharged throughthe spouts 26 and will be deposited on the conveyer 64 and thence directed stated. i
